So if you look in my other thread titled "Something wrong with fish's tail" or something like that maybe you can look at the pictures and give me your opinion on whats wrong with Kwimby. Someone said tail biting. Either way I'll be giong to the store today to make a sort of first aid kit for my bettas. What will I need to put in it and what will help Kwimby with his alleged tail biting.

Note: Please look at the pictures. I'm not sure if it's tail biting or not. I've only had one person respond.
